### Evaporator and Gradient Control

... Gradient control is an approach to achieve optimal operation. The basic idea is that if the ... zero, then the overall system will operate at optimal condition.Another novalty of the work is to propose ... cascade structure to deal with conditionally active constraints in optimizing control. To work with constraints, anti-windup ...

### Gradient for Triangulated Data

... or TRIGRADIENT(TRI,X,Y,Z,'vertex') returns numerical gradients of the function ... the vertices of the triangles specified in TRI. dFx and dFy are column vectors having the same ... where the triangles are defined by the M-by-3 face matrix TRI, such as that returned by DELAUNAY. ... vertex vectors to define ...

### central_diff

... The central_diff function calculates ... numeric gradient using the second-order accurate central difference formula for unevenly spaced coordinate data. It ... similar fashion to the MATLAB function, gradient, except that it permits only one independent variable, ...

### Hillshade

... Function to calculate hillshade for ... digital elevation model. Derives slope and aspect in radias to calculate shading value between ... given lighting angle and altitude.Altitude (angle above ground ... and angle (direction/aspect) of lightsource can be given via args.Derived using ...

### Skeleton in 3D

... The script uses distance transform instead of thinning base as the primary method ... for skeletonization.The method is sensitive to the value of the user ... .An alternative approach to 3D skeletonization that use the gradient and divergence of the ... distance transform is also given. Demands ...

### Inverse (integrated) gradient

... different methods, from cumtrapz, and an integrated cubic spline, plus ... several finite difference methods.In higher dimensions, only ... finite difference/linear algebra solution is provided, but it is fully ... least squares solution is generated. ...

### A Better Gradient

... need NOT be EQUALLY spaced. If ... need NOT be equally spaced. The number of elements in ... must equal the number of rows in F, i.e., size ... contains the x-axis data points and vector ... contains the y-axis data points. ...

### Inverse Gradient

... INVGRADIENT Basically the opposite of gradient(), aka Inverse Gradient.F ... reverses GRADIENT(F), where unit spacing is assumed.F ... DC offset of the integrated function is arbitrary. Also,INVGRADIENT is limited to 2-dimensions at the moment, ie ... no 3-dimensional matrices, or vectors. If dFx and dFy aren ...

### Neural networks with matrix inputs

... In some tasks matrix inputs occur naturally. In this package you will ... linear combination of sine functions, in each activation function ... function is done by gradient descent with inertia or extreme learning machine approach. This model is ... MATLAB Release: R2006a ...

### Movingslope

... The gradient function in Matlab allows you to compute the slope of ... The gradient function in Matlab allows you to compute the slope of ... noisy one, then gradient will also be noisy.This tool will generate and ... moderately low order polynomial regression model in ...

### cpcg

... x, error, iter, flag ... x, error, iter, flag ... x, error, iter, flag ... and default vaules will be used.cpcg.m solves the symmetric positive definite Toeplitz linear system Ax ... have to be SYMMETRIC POSITIVE DEFINITE.input ...

### Minimize a Function of Several Variables

... that minimizes FUN ... scalar result. Use an anonymous or nested function to supply parameter values to FUN.Options is an ... optional structure that defines algorithm behavior. If Options is empty or not given, default Options are ... set values in Options structure based on the Name ...

### DIFFERENT

... GRADIENT approximates derivatives using centered difference quotients.This is fast but not very accurate for ... non-uniform grids, where differences are not properly centered. DIFFERENT uses ... Forward plus backward minus centered difference quotients.This is more accurate for non-uniform grids. The ...

### Automatic Numerical Differentiation

... The DERIVESTsuite now provides automatic numerical differentiation for both scalar and vector valued functions. Tools ... up to 4th order) of ... provided, as well as the gradient vector, directional derivative, Jacobian matrix, and Hessian matrix. Error estimates are ...

Scripting matlab gradient programming is written in computer programming languages that is typically interpreted and can be typed directly from a keyboard. Matlab gradient scripts are often distinguished from executable files. This matlab gradient scripts are safe to use virus free and spyware free.
